(FIELD TESTING)Dampen inside of cone and place it on a smooth, moist, non-absorbent, level surface large enough to accommodate both the Slump test is the most commonly used method of measuring consistency of concrete which can be employed either in laboratory or at site of work. If a ided falling away or shearing off of concrete from one side or ; portion of the mass occurs, disregard the testImmediately measure the slump the vertical distance between the top of the mold and the 2 Dampen inside of cone and place it on a smooth, moist, non-absorbent, level surface large enough to accommodate both the slumped concrete and the slump cone. If this test is being carried out in the field, the sample mixed concrete shall be obtained. Standards: ASTM C and BSPrinciples Slump test is the most commonly used method of measuring consistency of concrete which can be employed either in laboratory or at site of work on the slump plate. Any slump specimen which collapses or shears off laterally gives incorrect result and if this occurs the test shall be repeated with another sample. Application() Very low. The slump plate should be clean, firm, leve. The slump test is done to make sure a concrete mix is workable. 'rodding'times. Due to this fact, it has been widely used for workability tests since The slump is carried out as per procedures mentioned in ASTM C in the United States, IS– in India and EN in Europe test. and non-absorbent. rm the slum firmly on the footpieces and fill 1/3 the volume of the c. Very dry mixes used in paving machines with high-powered vibration SLUMP TEST PROCEDURE. The test itself is controlled by the The test involves the measurement of concrete workability by taking a representative sample of wet concrete and measuring its slump after removal of a metal mould which This test is performed to check the consistency of freshly made concrete. If, in the repeat test also, the specimen should shear, the slump shall be measured and the fact that the specimen sheared, shall be recordedVideo Slump Cone Test Performing Slump test Procedure. Collect a sample of concrete to per. The measured slump must be within a Scope* This test method covers determination of slump of hydraulic-cement concrete, both in the laboratory and in the fieldThe values stated in either inch The concrete slump test measures the workability of fresh concrete by indirectly assessing the shearing resistance of the plastic concrete under its own weight. It is not a suitable method for The test is used for concrete with a target slump of betweenand mm, outside of these values alternative test methods should be used. b The slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Stand or, foot pieces throughout the test procedure to hold the cone firmly in placeFill cone 1/3 full by volume and rodtimes with 5/8-inch-di-ameter x inch-long hemispherical Workability of Concrete by Slump Test Order by Phone/ Order Online: Slump, in (mm) Degree of Workability Application () Very low Very dry mixes used in paving machines with high-powered vibration outside circumference of concrete after flowing from the slump conespread, n—the distance of lateral flow of concrete during the slump-flow teststability, n—the ability of a concrete mixture to resist segregation of the paste from the aggregatesviscosity, n—resistance of a material to flow under an applied Laboratory –Concrete TechnologyTests on Fresh Concrete: Slump Test Objective To determine the relative consistency of freshly mixed concrete. ne with the sample. Commence the slump test as soon as possible after sampling of concrete as per standard procedure described in ChapterPreparation of sample for test. Empty the sample from the container onto the sampling try. The test Specifications for Concrete Slump Test ApparatusReference IS (Part 2): (First revision) Fresh Concrete— Methods of Sampling, Testing and AnalysisPartDetermination of Consistency of Fresh ConcreteProcedure a. The slump test is the most simple workability test for Workability of Concrete by Slump Test. Rodding means to push a steel rod in and out of the concrete to compact it It does not measure the workability of concrete but it is very useful in detecting variations in the Concrete slump test is carried out from batch to batch to check the uniform quality of concrete during construction. Thoroughly mix the sample by shovelling to form a cone on the Complete the slump test, from the start of filling the mold through the removal of the mold, in 2½ minutes. Slump, in (mm) Degree of Workability. One test which measures the consistency of concrete is the slump test. Compact the concrete by.
